What did you want to be when you were a little girl?

In six words or less, what do you do all day at work?

Create more Cinderella moments.

What was the hardest part of launching Rent the Runway?

For someone like me who has always been Type A—and had a clear path towards achieving my goals—coping with the uncertainty of a path to entrepreneurship, and the initial post-college years worrying whether or not I would find work I could be passionate about, was challenging. I was convinced that I would find something, but I didn't have the right concept to pursue, just yet. What toolbox of skills would I need? What should I do in the meantime? How do I go after the right ideas? How would I stay motivated in the meantime? These were all questions I repeatedly asked myself.

Best advice for someone looking to take the leap into starting their own company or get their foot in the door?

Leverage your network, get feedback from friends and test out your idea directly with consumers in order to gain feedback that helps you tweak your concept. If you can get someone to put their money where their mouth is, that's the best validation. Listen more than you talk, and don't waste time with a business plan because flexibility is key to success in entrepreneurship.

The company-wide events with my amazing team, including a pirate-themed boat cruise in the East River, company Olympics at our warehouse in New Jersey and a day trip to a nearby ski mountain! I had always been someone who was more inclined to leave work at the office, but the wonderful team at Rent the Runway is like family. They are so hard-working, yet fun, and we have shared so many special moments in creating this company together. It has also been incredible to be in an environment that is predominately female, and to be able to bring outside interests in fashion and fitness into the office (rather than talking sports in male finance environments), all the while knowing what a hardcore group of women this is.

When I was younger, I always wanted to be Wonder Woman! She could do anything and never break a sweat and she had those FIERCE gold cuffs! At times, I do feel like I've become a version of her with the amount I do in a day, but I know it's only human to make mistakes and ask for help. One person cannot do everything alone. A strong support system is essential.

What was the most challenging moment in your career?

The most challenging and rewarding moment was when I decided to leave a successful 17 year career at Creative Artists Agency to start DreamDry. I was taking a chance, building a brand from the ground up, but I could not be more satisfied than I am today.

Tears of joy, for sure. Otherwise, never.

Deciding I had to follow my path and believe in my vision of my network. I kept going when I heard a lot of no's—until I heard a yes. Now, it's up to me to keep the vision of PowerwomenTV going and create a business model and culture I will be proud of—that also represents today's modern woman.

Yes, but deal with the issue, and move on. I am building a woman's network with an all woman staff. We aren't robots and aren't one-dimensional.

Trust yourself. Don't take a job you know you will hate. And don't listen to other people. They don't know what lives inside of you. Keep going and believe in your life vision.
